Die neuen Verbindungen lassen sich analog bekannten Verfahren der Herstellung von Azoverbindungen oder der Acylierung von entsprechenden Amino-Ausgangsverbindungen herstellen, so beispielsweise durch Diazotierung der entsprechenden Anilinverbindung und Kupplung mit der entsprechenden Aminonaphtholverbindung als Kupplungskomponente, die entweder bereits den aminosubstituierten Chlortriazinylrest enthält oder aber an die Aminogruppe einen Dichlortriazinylrest gebunden enthält, wobei im letztgenannten Falle die daraus gebildete Azoverbindung mit der Dichlortriazinylaminonaphtholdisulfonsäure-Kupplungskomponente gegebenenfalls anschließend mit einem entsprechenden primären oder sekundären Amin zur neuen Azoverbindung acyliert werden kann. Die neuen Azoverbindungen stellen sehr wertvolle Farbstoffe dar, die faserreaktive Eigenschaften besitzen und auf Cellulosefasermaterialien wie auch auf synthetischen und natürlichen Polyamidfasermaterialien wertvolle, farbechte und farbstarke Färbungen und Drucke liefern.Water-soluble azo compounds, of the general formula <IMAGE> and their salts, in which Y represents a chlorine atom or a radical of the formula -? - X, in which R represents a hydrogen atom or an alkyl group of 1 to 4 carbon atoms and X represents an alkyl group of 1 to 6 carbon atoms, which is substituted by a carboxylic acid group or sulfonic acid group, or represents the phenyl radical, which is substituted by one or two sulfonic acid and / or carboxylic acid groups, and Z for the vinyl, β-thiosulfatoethyl or β -Sulfatoethyl group and in which the second sulfonic acid group in the naphthalene radical is bonded in the m or p position to the acylated amino group, this sulfo group being in the p position if Y is chlorine. The new compounds can be prepared analogously to known processes for the preparation of azo compounds or the acylation of corresponding amino starting compounds, for example by diazotization of the corresponding aniline compound and coupling with the corresponding aminonaphthol compound as coupling component which either already contains the amino-substituted chlorotriazinyl radical or to the amino group contains a dichlorotriazinyl radical, in the latter case the azo compound formed therefrom with the dichlorotriazinylaminonaphtholdisulfonic acid coupling component can then optionally be acylated with a corresponding primary or secondary amine to form the new azo compound.

Gegenstand der vorliegenden Erfindung ist deshalb auch die Verwendung der erfindungsgemäßen Azoverbindungen
der allgemeinen Formeln (1) zum Färben von hydroxy-und carbonamidgruppenhaltigen Materialien bzw. Verfahren zu deren Anwendung auf diesen Substraten. Eingeschlossen sind hierbei die Massefärbung, beispielsweise Folien aus Polyamid, und die Druckfärbung. Bevorzugt kommen die Materialien in Form von Fasermaterialien zur Anwendung, insbesondere in Form von Textilfasern, wie Garnen, Wickelkörpern und Geweben.The present invention therefore also relates to the use of the azo compounds according to the invention
of the general formulas (1) for dyeing materials containing hydroxyl and carbonamide groups and processes for their use on these substrates. This includes mass coloring, for example polyamide films, and printing coloring. The materials are preferably used in the form of fiber materials, in particular in the form of textile fibers, such as yarns, packages and fabrics.
Hydroxygruppenhaltige Materialien sind natürliche oder synthetische hydroxygruppenhaltige Materialien, wie beispielsweise Cellulosefasermaterialien oder deren Regeneratprodukte und Polyvinylalkohole. Cellulosefasermaterialien sind vorzugsweise Baumwolle, aber auch andere Pflanzenfasern, wie Leinen, Hanf, Jute und Ramiefasern; regenerierte Cellulosefasern sind beispielsweise Zellwolle und viskose Kunstseide.Materials containing hydroxyl groups are natural or synthetic materials containing hydroxyl groups, such as cellulose fiber materials or their regenerated products and polyvinyl alcohols. Cellulose fiber materials are preferably cotton, but also other vegetable fibers, such as linen, hemp, jute and ramie fibers; Regenerated cellulose fibers are, for example, cellulose and viscous rayon.
Carbonamidgruppenhaltige Materialien sind beispielsweise synthetische und natürliche Polyamide und Polyurethane,insbesondere in Form der Fasern, beispielsweise Wolle und andere Tierhaare, Seide, Leder, Polyamid-6,6, Polyamid-6, Polyamid-11 und Polyamid-4.

Die erfindungsgemäßen Farbstoffe lassen sich auf den genannten Substraten, insbesondere auf den genannten Fasermaterialien, nach den für wasserlösliche Farbstoffe, insbesondere für faserreaktive Farbstoffe, bekannten Anwendungstechniken applizieren und fixieren.The dyes according to the invention can be used on the substrates mentioned, in particular on the fiber materials mentioned, according to the applications known for water-soluble dyes, in particular for fiber-reactive dyes apply and fix manure techniques.
So erhält man mit ihnen auf Cellulosefasern nach den Ausziehverfahren aus langer Flotte unter Verwendung von verschiedenstens säurebindenden Mitteln und gegebenenfalls neutralen Salzen, wie Natriumchlorid oder Natriumsulfat, sehr gute Farbausbeuten sowie einen ausgezeichneten Farbaufbau. Man färbt bei Temperaturen zwischen 20 und 105°C, gegebenenfalls bei Temperaturen bis zu 120°C unter Druck, gegebenenfalls in Gegenwart von üblichen Färbereihilfsmitteln, in wäßrigem Bad. Man kann dabei so vorgehen, daß man das Material in das warme Bad einbringt und dieses allmählich auf die gewünschte Färbetemperatur erwärmt und den Färbeprozeß bei dieser Temperatur zu Ende führt. _Die das Ausziehen des Farbstoffes beschleunigenden Neutralsalze können dem Bade gewünschtenfalls auch erst nach Erreichen der eigentlichen Färbetemperatur zugesetzt werden.They give you very good color yields and excellent color build-up on cellulose fibers using the exhaust process from a long liquor using a wide variety of acid-binding agents and optionally neutral salts, such as sodium chloride or sodium sulfate. Dyeing is carried out at temperatures between 20 and 105 ° C., if appropriate at temperatures up to 120 ° C. under pressure, if appropriate in the presence of customary dyeing auxiliaries, in an aqueous bath. The procedure can be such that the material is introduced into the warm bath and this is gradually heated to the desired dyeing temperature and the dyeing process is completed at this temperature. _The neutral salts that accelerate the extraction of the dye can, if desired, only be added to the bath after the actual dyeing temperature has been reached.
Nach dem Klotzverfahren werden auf Cellulosefaser ebenfalls ausgezeichnete Farbausbeuten und ein sehr guter Farbaufbau erhalten, wobei durch Verweilen bei Raumtemperatur oder erhöhter Temperatur, beispielsweise bis zu etwa 60°C, durch Dämpfen oder mit Trockenhitze in üblicher Weise fixiert werden kann.After the padding process, excellent color yields and a very good color build-up are also obtained on cellulose fiber, which can be fixed in the usual way by staying at room temperature or elevated temperature, for example up to about 60 ° C., by steaming or with dry heat.
Ebenfalls nach den üblichen Druckverfahren für Cellulosefasern, die einphasig, beispielsweise in Anwesenheit von Natriumbicarbonat oder einem anderen säurebindenden Mittel in der Druckpaste und durch anschließendes Dämpfen bei 100 bis 103°C, oder zweiphasig, beispielsweise mit neutraler oder schwach saurer Druckfarbe bedruckt und dann entweder durch Hindurchführen durch ein heißes elektrolythaltiges alkalisches Bad oder durch Uberklotzen mit einer alkalischen elektrolythaltigen Klotzflotte und anschließendem Verweilen dieses behandelten Materials oder anschließendem Dämpfen oder anschließender Behandlung mit Trockenhitze, durchgeführt werden können, erhält man farbstarke Drucke mit gutem Stand der Konturen und einem klaren Weißfond. Der Ausfall der Drucke ist von wechselnden Fixierbedingungen nur wenig abhängig. Sowohl in der Färberei als auch in der Druckerei sind die mit den erfindungsgemäßen Verbindungen erhaltenen Fixiergrade sehr hoch. *) sehrAlso according to the usual printing processes for cellulose fibers, which are printed in one phase, for example in the presence of sodium bicarbonate or another acid-binding agent in the printing paste and by subsequent steaming at 100 to 103 ° C, or in two phases, for example with neutral or weakly acidic printing ink and then either by Passing through a hot electrolyte-containing alkaline bath or by padding with an alkaline electrolyte-containing pad liquor and then staying this treated material or subsequent steaming or subsequent treatment with dry heat, you get strong prints with good shape of the contours and a clear white background. The Failure of the prints is only slightly dependent on changing fixing conditions. Not only in dyeing as ruckerei in the D fixing obtained with the compounds are very high. * ) very much
Bei der Fixierung mittels Trockenhitze nach den üblichen Thermofixierverfahren verwendet man Heißluft von 120 bis 200°C. Neben dem üblichen Wasserdampf von 101 bis 103°C kann auch überhitzter Dampf und Druckdampf von Temperaturen bis zu 160°C eingesetzt werden.Hermofixierverfahren When fixing by means of dry heat by the customary T processes, hot air from 120 to 200 ° C. In addition to the usual steam from 101 to 103 ° C , superheated steam and pressure steam at temperatures up to 160 ° C can also be used.
Die säurebindenden und die Fixierung der Farbstoffe auf den Cellulosefasern bewirkenden Mittel sind beispielsweise wasserlösliche basische Salze der Alkalimetalle und ebenfalls Erdalkalimetalle von anorganischen oder organischen Säuren oder Verbindungen, die in der Hitze Alkali freisetzen. Insbesondere sind die Alkalimetallhydroxide und Alkalimetallsalze von schwachen bis mittelstarken anorganischen oder organischen Säuren zu nennen, wobei von den Alkaliverbindungen vorzugsweise die Natrium- und Kaliumverbindungen gemeint sind. Solche säurebindenden Mittel sind beispielsweise Natriumhydroxid, Kaliumhydroxid, Natriumcarbonat, Natriumbicarbonat, Kaliumcarbonat, Natriumformiat, Natriumdihydrogenphosphat, Dinatriumhydrogenphosphat, Natriumtrichloracetat, Wasserglas oder Trinatriumphosphat.The acid-binding agents and the fixation of the dyes on the cellulose fibers are, for example, water-soluble basic salts of the alkali metals and also alkaline earth metals of inorganic or organic acids or compounds which release alkali in the heat. In particular, the alkali metal hydroxides and alkali metal salts of weak to moderately strong inorganic or organic acids are to be mentioned, the alkali compounds preferably referring to the sodium and potassium compounds. Such acid-binding agents are, for example, sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, potassium carbonate, sodium formate, sodium dihydrogen phosphate, disodium hydrogen phosphate, sodium trichloroacetate, water glass or trisodium phosphate.
Durch die Behandlung der erfindungsgemäßen Verbindungen mit den säurebindenden Mitteln, gegebenenfalls unter Wärmeeinwirkung, werden die erfindungsgemäßen Verbindungen (Farbstoffe) chemisch an die Cellulosefaser gebunden; insbesondere die Cellulosefärbungen zeigen nach der üblichen Nachbehandlung durch Spülen zur Entfernung von nicht fixierten Farbstoffanteilen ausgezeichnete Naßechtheiten, zumal sich nicht fixierte Farbstoffanteile leicht wegen ihrer guten Kaltwasserlöslichkeit auswaschen lassen. Die Färbungen auf Polyurethan- und Polyamidfasern werden üblicherweise aus saurem Milieu ausgeführt. So kann man beispielsweise dem Färbebad Essigsäure und/oder Ammoniumsulfat und/oder Essigsäure und Ammoniumacetat oder Natriumacetat zufügen, um den gewünschten pH-Wert zu erhalten. Zwecks Erreichung einer brauchbaren Egalität der Färbung empfiehlt sich ein Zusatz an üblichen Egalisierhilfsmitteln, wie beispielsweise auf Basis eines Umsetzungsproduktes von Cyanurchlorid mit der 3-fach molaren Menge einer Aminobenzolsulfonsäure und/oder einer Aminonaphthalinsulfonsäure und/oder auf Basis eines Umsetzungsproduktes von beispielsweise Stearylamin mit Äthylenoxid. In der Regel wird das zu färbende Material bei einer Temperatur von etwa 40°C in das Bad eingebracht, dort einige Zeit darin bewegt, das Färbebad dann auf den gewünschten schwach sauren, vorzugsweise schwach essigsauren, pH-Wert nachgestellt und die eigentliche Färbung bei einer Temperatur zwischen 60 und 98°C durchgeführt. Die Färbungen können aber auch bei Siedetemperatur oder bei Temperaturen bis zu 120°C (unter Druck) ausgeführt werden.By treating the compounds according to the invention with the acid-binding agents, if appropriate with the action of heat, the compounds (dyes) according to the invention are chemically bound to the cellulose fiber; in particular the cellulose dyeings show excellent wet fastness properties after the customary aftertreatment by rinsing to remove unfixed dye components, especially since unfixed dye components can easily be washed out because of their good solubility in cold water. The dyeings on polyurethane and polyamide fibers are usually carried out from an acidic environment. For example, the dyebath can be acetic acid and / or ammonium Add sulfate and / or acetic acid and ammonium acetate or sodium acetate to get the desired pH. In order to achieve a useful levelness of coloration, it is advisable to add conventional leveling aids, such as, for example, based on a reaction product of cyanuric chloride with 3 times the molar amount of an aminobenzenesulfonic acid and / or an aminonaphthalenesulfonic acid and / or on the basis of a reaction product of, for example, stearylamine with ethylene oxide. As a rule, the material to be dyed is introduced into the bath at a temperature of approx. 40 ° C, agitated there for some time, the dyebath is then adjusted to the desired weakly acidic, preferably weakly acetic acid, pH value and the actual dyeing at one Temperature between 60 and 98 ° C carried out. The dyeings can also be carried out at boiling temperature or at temperatures up to 120 ° C (under pressure).
In der Regel werden die hydroxygruppenhaltigen und/oder carbonamidgruppenhaltigen Fasermaterialien mit den erfindungsgemäßen Verbindungen der allgemeinen Formel (1) bei Temperaturen zwischen 60 und 105°C oder, falls erwünscht, auch bei Temperaturen bis zu 120°C gefärbt, sofern nicht zur Fixierung des Farbstoffes ein anderes Verfahren, wie die Fixierung mit überhitztem Wasserdampf oder mit Trockenhitze, angewendet wird.

Die erfindungsgemäßen Verbindungen der allgemeinen Formel (1a) zeigen dagegen eine erhöhte Faserreaktivität, so daß sie bereits vorteilhaft bei Temperaturen zwischen 20 und 60°C auf den Fasermaterialien fixiert werden können; dies schließt natürlich nicht aus, daß sie auch vorteilhaft in Applikations- und Fixierverfahren eingesetzt werden können, die bei Temperaturen oberhalb von 60°C arbeiten.As a rule, the fiber materials containing hydroxy groups and / or carbonamide groups are dyed with the compounds of the general formula (1) according to the invention at temperatures between 60 and 105 ° C. or, if desired, also at temperatures up to 120 ° C., unless the dye is fixed another method, such as fixation with superheated steam or dry heat, is used. The dye can also be fixed in the printing process using one of the fixing methods mentioned above at temperatures between 60 and 120 ° C. as the preferred temperature range. The compounds of the general formula (1), in which Y represents the formula radical - N RX, are preferably fixed in the dyeing and printing processes at one of the temperatures or temperature ranges above 60 ° C. indicated above. The compounds of the general formula (1a) according to the invention, on the other hand, show an increased fiber reactivity, so that they can already be advantageously fixed on the fiber materials at temperatures between 20 and 60 ° C .; this closes Of course, this does not mean that they can also be used advantageously in application and fixing processes that work at temperatures above 60 ° C.

Insbesondere die Färbungen und Drucke auf Cellulosefasermaterialien besitzen eine hohe Farbstärke, wie bereits erwähnt, darüber hinaus eine gute Lichtechtheit und gute Naßechtheiten, wie Wasch-, Walk-, Wasser-, Seewasser-, Uberfärbe-, Naßlicht-, saure und alkalische Schweiß- sowie saure und alkalische Schweißlichtechtheiten, desweiteren eine gute Plissierechtheit, Bügelechtheit und Reibechtheit sowie eine hohe Dampfbeständigkeit. Zudem zeigen sie sehr echte Eigenschaften bezüglich eines Ausblutens im feuchten oder nassen Zustand und bezüglich eines. Abfleckens oder Anblutens von Begleitgewebe oder beiliegendem Gewebe, beispielsweise im Druck. Fixierte Färbungen können im nassen Zustand unbedenklich, ohne Veränderung des Farbtons, aufeinander liegend gelagert werden.The dyeings and prints produced with the compounds of the general formula (1) according to the invention are distinguished by very clear shades. In particular, the dyeings and prints on cellulose fiber materials have a high color strength, as already mentioned, moreover good light fastness and good wet fastness properties, such as wash, walk, water, sea water, overdye, wet light, acidic and alkaline sweat and Acid and alkaline perspiration fastness, furthermore good pleating fastness, ironing fastness and rubbing fastness as well as a high steam resistance.
